面临着节省资源的时代,迫切需要重新研究机械和装置之类的设计方法。即开始推广对结构零件尽可能地采用廉价的金属材料,并试图用热处理的方法提高其性能。机械构件的质量,可分尺寸精度与使用寿命两大部份。前者属于机械加工范围,后者则属于热处理或表面处理范围。本文中所提出的抗磨损诸问题,在零件的耐久性方面占最重要的地位。目前虽然发展了很多处理技术,但由于金属的磨损机理非常复杂,仍未得到恰当的应用。本文则介绍一些 Faced with the era of resource conservation, there is an urgent need to re-study design methods such as machinery and devices. That is to begin promoting the use of inexpensive metal materials for structural components as much as possible and attempting to improve their performance by heat treatment. The quality of mechanical components can be divided into two parts of the dimensional accuracy and service life. The former belongs to the machining range, the latter belongs to the scope of heat treatment or surface treatment. The anti-wear problems presented in this paper are paramount to the durability of the part. At present, although a lot of processing technologies have been developed, due to the complicated wear mechanism of metal, proper application has not yet been made. This article introduces some
